Hoop diameter changes the whole vibe:
Small (15-20mm): Subtle, professional, barely peek out from your hair. Good for conservative workplaces or if you want diamonds without drama.
Medium (25-35mm): The sweet spot for most people. Noticeable but not over the top. Works for office and evening.
Large (40mm+): Statement pieces. Great for nights out, not ideal for contact sports or small children who grab things.
The weight matters too. Bigger hoops with more diamonds get heavy. If you have sensitive ears or plan to wear them all day, factor in comfort.
